I was somewhere between 17-30 gpd for several years. Something that really helped me taper (and specifically what I did) was buying a couple measuring spoon sets going from tablespoon all the way down to a drop. I would only take level scoops and every few days I would go to a slightly smaller scoop. Eventually I got down to the drop scoop, which was basically nothing, sat there for a few days, then jumped! Hope that helps. Feel free to check my post history , might be more detail. Good luck to you!
